Hello again @Francesco, @Andrea Rovai and other developers and users. Let's talk here about usability of your Android builds. Here I will describe my troubles with android builds. Firstly I wil tell you about my hardware. I have: Udoo Quad board rev.D SanDisk Extreme SDhc UHS Speed Class 1 Samsung 720p connected with HDMI cable I am not developer so I will make review from customer point of view. Today I will test Android builds. Firstly I download ANDROID 4.4.2 KITKAT - Release Date: 2015-01-28 - Release Version: 4.4.2-1.0 (old enough, but it is the latest of official android build ) I switch resolution to 1280x720 (actually I need 1024x768, but it automatically switches to 720p) with the following command found in manual: setenv bootargs console=ttymxc1,115200 init=/init video=mxcfb0:dev=hdmi,1024x768M@60,if=RGB24,bpp=32 video=mxcfb1ff video=mxcfb2ff fbmem=28M vmalloc=400M androidboot.console=ttymxc1 androidboot.hardware=freescale mem=1024M How can I get 1024x600 (best) or 1024x768 resolution? I notice red board around the screen when board lags. How can I disable that behaviour? I boot up board go to menu, launch browser. Interface works smooth and I experience no problems. [del] I switch Android to ART from dalvik.[/del] (switched back again) Next I decide to install gapps with this manual, and login to my account After that board begins to lag, but i think that because of background updates of gapps so not the problem. I install youtube, try to launch it and...interface hangs, adb works without problem. I reboot it, launh youtube and try to playback first video. It's lagging sometimes and overall picture is not so smooth. After swithcing to full screen lags appears more noticeble. I get sound synchronisation problems and overall slowdown of interface. Next I install google maps. Try to launch it. After couple of minutes maps () maps launches and...board hangs again like earlier. I reboot it. After reboot I launch maps again. This time successfully. Performance was pretty good, but then it begins to lag and i was kicked off to homescreen. After few attempts I decided to go back to dalvik. After reboot I try google maps - it works and youtube - works too (performance wasn't get better). Install angry birds 2 - get lags and haven't sound at all. Then-menu-lags-choose audio to hdmi (it was hdmi but I click hdmi again) and get sounds back )) Two videos included: Not too bad and I try to use it later without gapps, maybe it would run smoother (I hope), but unexpected hangouts and kick offs from application is irritating Let's go to ANDROID 6.0.1 MARSHMALLOW - Release Date: 2016-07-20 - Release Version: 6.0.1 Beta Firstly - I can't switch hdmi resolution from 1080p. If I try to enter same command as above I get bootloop. How can I switch resolution? Next - I would like to know what options should I install in developers options for better performance? I will try to use it whithout gapps because my previous experience with gapps was terrible. Even without gapps performance in launcher is much worse that was in 4.4. I download several apps and notice that installation became significantly slower too. I launch Yandex maps and after 20 seconds it freeze. Cursor lags. Next I was kicked off from app. I tried several other apps with variable success. Overall performance of the system is murch worse and lags is annoying. No video today because it's too late already. To be continued... And one small quote from your Kickstarter campaign: "Running Android Android 4.0.4 Ice Cream Sandwich runs smootly on UDOO giving you all the features of an Android device (further Android releases will be available at the time of distribution)."
